A Coolify Alternative
Without the Security Vulnerabilities
Coolify disclosed 11 critical CVEs in January 2026. sh0 has undergone 2 independent security audits with 88 issues found and fixed -- zero known critical vulnerabilities.
The quick verdict
sh0 gives you the same self-hosted deployment workflow as Coolify -- git push deploys, auto-SSL, managed databases -- but in a single 27 MB Rust binary that idles at 50 MB RAM, with 2 independent security audits and a built-in Claude AI assistant.

Why developers switch
Real pain points from Coolify users -- and how sh0 solves them.
"Coolify killed my requests on every deploy"
sh0 blue-green deploys swap the container behind the proxy. Zero requests dropped, zero downtime -- even on a $4/mo VPS.
"CVE-2025-64420 exposed my SSH key"
sh0 has 2 independent security audits with 88 issues found and fixed. Secrets are encrypted with AES-256-GCM. SSH keys never leave the server.
"500 MB RAM before deploying anything"
sh0 idles at ~50 MB. A single Rust binary replaces the multi-container stack. Your $4/mo VPS has room left for your actual apps.
